Basically, Andy Tweed has re-raised the issue about 'that Arctic gull' that was causing havoc this winter in and around the London area (was there only one bird??). Seems like investigations (assuming correct identifications have been made by the 'natives') have revealed that some Glaucous-winged Gulls can be relatively fine billed, approaching Herring Gull in bill structure. Perhaps these are small females? Also it comes to light that some Glaucous-winged Gulls can have white primaries- which may be due to variation or perhaps, especially in April, could be due to bleaching. Something else that came up (new for me) is that the grey mantle feathers shown on the Beddington bird are actually quite a good feature of Glaucous-winged Gull.
The post below, shows birds which have been identified as Glaucous-winged Gull which are non-classics in various features which are pertinent to the Beddington Bird.
The jury is still out on this one, I reckon. For me, I simply do not have the knowledge or experience to make a conclusion but am certainly considering the most likely possibilities being a Glaucous-winged Gull hybrid/unsual variant Glaucous-winged Gull/other hybrid throwing up a 'look-alike'- can it go any further?

Quite a few young birds about at Beddington, especially Starlings. Carrion Crows, Magpies and a Peregrine were hunting the new fledglings. A couple of Buzzards were hanging around today. A Lesser Whitethroat singing along the path, plenty of Reed Warblers, Whitethroats and 2 singing Sedge Warblers, 2 singing Reed Buntings and good numbers of Greenfinches. Mute Swans have got 2 new cygnets and a few Gadwalls are prospecting.

2. The latest bird, photo taken on 13th May. A full breasted bird, overall white in tone, limited 'ghost' tail band and complete primaries on left and right wing (have to believe me about the left wing).
3. Same bird as above (plate 2), 13th May.
4. 1st summer Iceland Gull from 18th April. Some grey feathering on the mantle.
5. 1st summer Iceland Gull, 18th April, showing missing primary on left wing and also a fairly obvious tail band.

Well that weather didn't do anything spectacular yet. The only migrant of note was a Greenshank. The 1st summer Iceland Gull was still present, also one Peregrine, three Common Sandpipers and about 60+ Swift. Three male Gadwalls were present on the lake. About 20+ Black-headed Gulls about- mainly first summers. Still about 1000+ large gulls- mainly Herring with about 10% L.B.B Gull.

Also it comes to light that the Lea Valley is pretty poor for Wood Sandpipers (only two in 20 years) and a record at the EIDB would warrant a flag flying for Paul Hyland- so perhaps the small number of Wood Sands that pass through London generally follow the Beddington to Brent line. There are only two records from Regents Park (August 1969 and 1977) so obviously not a favoured stop over site on the (hypothetical) flight line.
That small number of London Wood Sands may well be on the decrease as at Beddington (a key site), since the landfill operations, the status has changed from five to six records of up to two to three annually to, for example, no records in 2003 and only one in 2005. On August 14th 1999 there were ten on the farm- since then the sludge beds have decreased in number to make way for landfill.

Breeding positions are being taken swiftly at the moment. Sand Martins are busy nesting in the Sand Martin bank (5-6 pairs), there is a pair and a spare of Gadwall, only a male Shelduck, one to two pairs of Little Grebe, perhaps 10 pairs of Lapwing and Grey Heron juveniles are already out- there is about 30+ Grey Herons on the farm. Must be 60 pairs of Whitethroat on site.
So far this spring at Beddington:
UP AND OKAY: Buzzard, Red Kite, Whitethroat, Reed Warbler, Sedge Warbler, House Martin, Swallow, Lesser Whitethroat,
DOWN or OUT: Willow Warbler, Turtle Dove, Spotted Flycatcher, only one Cuckoo, wader numbers are low.
